Ansible Kubernetes HA Cluster

🛠️ Ansible Kubernetes HA Cluster – Infrastructure Automation Project

🌐 Project Overview

This project is a fully automated Infrastructure as Code (IaC) solution using Ansible to provision a Highly Available (HA) Kubernetes Cluster. It demonstrates end-to-end automation of a production-ready Kubernetes environment with multi-master architecture and HAProxy-based load balancing.

⚙️ Technologies Used

• Ansible – for automated provisioning and orchestration

• Kubernetes (HA) – with 3 control plane nodes and worker nodes

• HAProxy – external load balancer for high availability of API server

• Containerd – container runtime for lightweight and secure workloads

• Ubuntu 22.04 / 24.04 – as the OS base on all nodes

• (Optional) Keepalived + Floating IP – for local failover/load balancer setup

📌 Key Features

• 🔧 Modular Ansible roles (common, containerd, kubernetes, lb-haproxy, master/worker)

• 🔄 One-command cluster setup and teardown (playbook.yml and reset-k8s.yml)

• 🧩 Clear inventory structure with IP mapping and SSH configuration

• 💡 Designed for easy extensibility and reusability

• 📂 Comprehensive documentation with directory tree and usage steps

• 🛡️ Secure, consistent deployment following DevOps best practices

🎯 Goals & Purpose

• Showcase real-world skills in DevOps, IaC, and Kubernetes automation

• Create a reusable template for production or lab Kubernetes HA clusters

• Demonstrate infrastructure design thinking and tool integration

📁 Project Output

• A working multi-node Kubernetes HA cluster with load balancing

• Full Ansible playbook repo including:

  • playbook.yml – main setup automation

  • reset-k8s.yml – cluster reset automation

  • roles/ – organized task files per component

  • inventory/ – group-based host inventory

• Professional README.md with badges, usage guide, and structure
